Background / History

Keima was originally a student at Maijima Academy who spent his time playing galgames and publishing walkthroughs online. He had built a reputation as the “God of Conquest,” claiming 10,000 conquered heroines and nearly 5,000 completed games. After receiving a provocative message challenging him to conquer any girl, he accepted the contract without hesitation. 1

The contract drew Keima into another world alongside Elsie, a demon civil servant posing as his younger sister. Their task is to make designated girls fall in love, thereby recovering fragments of the Creator God’s power and preventing a Void invasion from destroying parallel worlds. The mission must be completed within three years, before the targets graduate. 1 5

Keima enrolls in Advanced Nurturing High School’s Class D. Although distressed by the school’s confiscation of electronics and boarding rules, he treats the target-card system—complete with affection percentages and achievements—as a high-difficulty galgame interface and begins adapting his strategies to real people. 2 3

Appearance

Keima is a glasses-wearing male student whose lenses frequently reflect light when he makes a dramatic declaration or analyzes a situation. He is almost always seen holding or operating a game device. 3 11

• Carries handheld consoles and game cartridges in his pockets, sometimes more than one console at a time. 37
• Uses a waterproof case to keep gaming during swimming lessons. 35
• Can navigate from the classroom entrance to his seat while focused entirely on a game. 11

Personality

Keima openly considers the real world inferior to the “pure” world of games and treats other people’s opinions as inconsequential NPC dialogue. His intense focus on games makes him seem robotic, eccentric, and indifferent to conventional social expectations; he will play in class, negotiate directly with teachers for gaming rights, and reject requests that interfere with his playtime. 11 15

Despite this detachment, Keima is perceptive about people. He identifies Kikyo Kushida’s pleasant persona as a mask, recognizes Airi Sakura’s discomfort rather than forcing interaction, and accurately assesses Suzune Horikita’s flaws and strengths. His social methods are calculated, but he can show genuine patience, encouragement, and protectiveness when someone is vulnerable. 11 18 31 32 42

Keima distinguishes sharply between fiction and reality. While he frames relationships through game terminology, he rejects Elsie’s attempt to apply murder methods from mystery novels to real life and insists that games should not be conflated with reality. 18

• Airi Sakura — Classmate and mission target whose social anxiety Keima approaches patiently. He helps her shop for a camera, recognizes her identity as the model “Shizuku,” protects her from a threatening clerk, and becomes the focus of her increasingly intense affection. 18 21 42 46 47
